Costa Concordia salvage operation begins off the coast of the island of Giglio

Despite the violent capsizing, no major pollution has been detected in the waters near the ship. Fuel was siphoned out early in the salvage operation, but food and human waste are still trapped inside. Should the Concordia break apart during the rotation, or spew out toxic materials as it is raised, absorbent barriers were set in place to catch any leaks.Picture: VINCENZO PINTO/AFP/Getty Images
